I know this often gets discussed, but honestly I'd love for Shane to actually remain sober once you marry him. Or at least get an extended story after, to show how he betters his progress over time (like have a few scenes where it shows him slipping as is natural with addiction but then the whole community shows up to help him instead of just the player so he can keep on powering through it all). He may be the only character to have such a thing, but it'd be far more rewarding than just having him still get drunk and have his room be a mess 24/7.
